[Abstract:] Reports the arch of Coining Press No. 10 as cracked... 694
Mint of the United States at Philadelphia, Pa.,
Coiner’s Department,
July 25, 1882
Hon. A. Loudon Snowden,
Superintendent.
Sir;
I have the honor to state that the arch of Coining Press No. 10 has cracked in two, and
possible three, places, and that work upon it is liable to be suspended at any time.
The diagram indicates the cracks developed, the one shown by the x is supposed to exist
— those shown by the >-> can be easily discerned. I would respectfully suggest that arrangements
be made at once to replace this arch with a new one.
The arch of Press. No. 7 was replaced in 1878, the old arch of that Press cracked in April
of that year, and the crack increased so rapidly that work ceased on it very soon after the damage
was first discovered. It was proposed then to repair the arch, but the views, of our own
Machinists, and such competent and efficient ones outside, as Messrs. Orr, Hess & Morgan, and
Wm. Sellers & Co., were all opposed to attempting it. All agree it could be done, but when done
it would prove unsatisfactory, and the cost would be as much as a new arch. Mess. Sellers & Co.
said at that time, “Our experience in mending machines of this character is not such as to warrant
us in recommending an attempt to do so. Xx The coining presses as constructed will only do
their work efficiently if rigid and unyielding. The proper rigidity can best be obtained by solid
metal. Any attempt to patch up the press will introduce elements of weakness and elasticity and
will in our opinion cost more than a new cast iron arch.”
I am exceedingly sorry that this accident has occurred to this press. For over two years it
has worked so satisfactorily, as to cause all interested in it, much gratification. During the recent
suspension of work, it was taken apart to clean, and every portion of its machinery was found in
better condition than had ever been experienced with any of our presses.
There was absolutely nothing required to be done to any part of it, except cleansing, and
putting together again. When work was resumed the smoothness with which it performed its
task, was remarked.
I trust that a new arch may be ordered for this Press without delay.
Very Respectfully,
Your Obt. Servant
O.C. Bosbyshell, Coiner.
